Description
technical field [0001] The invention relates to the field of inverter detection, and more specifically relates to a high-power energy storage inverter current detection and control system. Background technique [0002] In the field of energy storage inverters, when the energy storage battery is charging or discharging, it is necessary to accurately control the current of the energy storage battery, especially in the charging control, the battery current detection is more important. Generally, there are two methods for battery current detection. One detection method is to use a single precision power small resistor to detect current, and the other is to use a single Hall current sensor to detect current, and the most commonly used method is to detect current through parallel resistors. [0003] However, the existing detection and control devices are not only inconvenient to install and position the resistors, but also not conducive to the connection to the inverter circuit, r...
